Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.44/day in the week to Aug 4 → 0.43/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
You play Ethelyn Dax, Galactic Bounty Hunter extraordinaire. Finally settling in for a long-awaited vacation on the resort world of Ctesiphon, the moment is ruined by the surprise arrival of the Black Death mercenary company.

Taking the capital city and every surrounding resort hostage as part of a payment dispute, the mercenaries expected to meet no physical resistance.
Ethelyn would be perfectly content to simply get her money back and leave the resort to sort things out with the mercenaries themselves, but as it turns out the force is led by a shadow from Ethelyn's own past that she can't simply let get away.

The Black Death mercenaries have brought so many troops, clones, drones, and mechs that they expect absolutely no resistance from the resort patrons. You will prove that complacency unfounded.
Take advantage of the mercenaries' inattention with Ethelyn's trusty Data-Spike, perforate them with the versatile Submachinegun, blast them around corners with the Gyrobuster's homing minirockets, or bring out the Jetgun to cut through heavy armor as if it were mere paper.
Ethelyn is highly nimble and can run circles around most enemies who will have to resort to overwhelming force to try and stop you. The game features seven mainline levels built in a non-linear layout allowing you to flank enemies and search for secrets.

Made in bits and pieces over the course of nearly a decade by a single developer on Linux using C/C++, OpenGL, and open-source Quake mapping tools, Ctesiphon's custom engine allows for the game to run reliably on low-spec systems. It's built to withstand large firefights with dozens of enemies, hundreds of blood spatter and bullet impact decals, and piles of giblets and scrap as you blow the enemies apart into clouds of particles and debris.
Ctesiphon has been developed on Linux first and supports virtually all controllers connected to it. On Windows only XInput-compatible controllers are supported natively, but others will work fine with SteamInput enabled. The big exception is for the Steam Deck and Steam Controllers, these won't be natively supported on Linux/SteamOS until after release but in the meantime they should work fine if you play the Windows build by setting compatibility to any version of Proton.

Gra jest naprawdę spoko. Trochę krótka, ale to, co jest daje radę. Projekty poziomów są ciekawe i zróżnicowane. Broń też ma kopa. Historia nie jest wybitna, ale daje radę. Z rzeczy, które mnie irytowały, wymienić należy, że strasznie dużo mechów wychodzi na nas w późniejszych etapach. Słuchanie tego odchrząkiwania i pociągania nosem przeciwników też nie nazwałbym czymś fajnym.
Came to this Game because Mutantleg (Zortch Developer) Recommended it. I enjoyed my time playing Ctesiphon, very challanging an Hard difficulty and above. The game is shorter then I expected with only 8 Levels. Probably take 2 to 3 hours to get through. (Means I can play though it faster though). Only Major Issue I had with the game was navigating some of the later levels, especially Map06: Comm Station. Its a great level, just finding the switches can be a tad annoying. And those in level secrets are very well hidden. (I did not even find half of them) The Game runs very fast and smooth and well, did not have any issues there. I Played though the game to completion 3 times on different Difficulty Levels. 1st: HARD 2nd: EXTRA HARD! 3RD: Super easy (Victory Lap)

This is a very special game and I'll be very disappointed if we don't see Ethelyn again. Don't know why steam is saying i refunded. Super did not do that, this game is amazing. Also, I really hope an OST is released.
bought the game because the blonde cutie of the thumbnail game is great too
Fun game. Nice weapons and good vibes. But too short and the boss is disappointing.
👍
Fun little shooter game, feels very good to play and doesn't overstay its welcome.

Great little shooter. Fun combat and guns. Good levels with lots of secrets. And the music is thematic and overall really awesome
[h2]I liked...[/h2] [list] [*]The gameplay - fast-paced arcade action while hunting for blue and yellow access cards like it's the 1990s again [*]The guns - there are some fun ones like auto-guided small missles or a water jet gun (this game's BFG) [*]The aesthetic - the game has a nice visual style that works well [*]The humor - it's a cheesy parody, I enjoyed the enemy dialogues and bizzare adverts [*]The custom engine - it ran flawlessly for me and I admire such level of dedication to the craft [/list] [h2]I didn't care for...[/h2] [list] [*]The robots - towards the end, the game leans too hard on these spongey, hard-hitting enemies; more variety would be better (for example, some kind of elite soldier or a helicopter attacking from outside through the windows of the last level) [*]The length and lack of more developed story - I wished the game was longer and we got more story; I enjoyed the cast, but the game doesn't do much with them [/list] [h2]Verdict[/h2] [i]Ctesiphon[/i] is a retro shooter that takes after its 90's inspiration in both good and bad ways - it's easy to pick up, fun to play, it has a sense of humor (I loved how enemy soldiers squeak when they detect you, it sounds like they're happy to see you :D), but it's also barebones in terms of story. I wished it was longer; not because of value, but because I enjoyed the cast and gameplay and wanted to see it developed further. As a one-man project, from the art down to the game engine level, it looks and runs great; I'll be keeping an eye on future projects from this guy. 8/10, would get stabbed by a cactus again.
